Design of Kawlewada Dam and its Components

Abstract

This paper presents the design and stability analysis of Kawlewada dam (a concrete gravity dam situated in kawlewada village of gondia district) and its components. Through, the demanding years, it has been observed that failures of dams due to many factors are common. So, it is the essential to analysis the various components, parts of dam against all its modes of failures, forces acting on it, uncontrollable disasters such as earthquake, disaster, etc. For this, the preliminary data of the dam required for design, such as control levels, dimensions, crest width, base width, etc. was collected through the Inspection Engineer, posted at Dhapewada Lift Irrigation Office, Tirora, Dist. Gondia. On the basis of collected data the elementary profile and practical profile of dam was estimated, further all the major and the minor force forces acting on dam were calculated, stability analysis of designed dam against all modes of failure and for various load combinations was carried out in STAAD PRO software and was checked for permissible limits. Design of spillway, stilling basin and earthen dam was also carried out for the designed dam. Further, canal originating from the dam and carrying water to culturable command area was also designed by taking care of peak discharge as required by crops.
